Abstract

Hot dip galvanized high strength bolts are widely used to bolted joints in steel structures. It is known that such bolts vary widely in torque coefficient. However, characteristics of torque coefficient are not clarified. In this paper, investigated is the 1730 of torque coefficient on the basis of the mill sheet date in order to clarify torque coefficient on hot dip galvanized high strength bolts. The mechanical property of such bolts is also investigated.
